The clustering method generates clusters reflecting current trend of recent topics. However, the problem with this clustering method is the setting of the exponential decaying factor parameter through which a document loses its value as time passes. In the clustering method, the parameter value is assumed a user-specified parameter and only one value is used for all types of documents regardless of which categories they are in. In this paper, we will show an analytical study on the real dataset. The objective of this study is to find the relationship between the decaying behavior of each document with their corresponding category types which will be helpful in the setting of parameter values in the novelty-based document clustering method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"381","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"375","bibliographicIssueDates":{"bibliographicIssueDate":"2006-07-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"78(2006-DBS-140)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T22:30:21.388143+00:00","created":"2025-01-18T22:51:31.978230+00:00","id":18932}
